the class Util method waitFor.

/**
 * Invoke the given {@code completed} supplier on a pooled thread approximately every {@code pollIntervalMs}
 * milliseconds until it returns true or {@code timeoutMs} milliseconds have elapsed.
 * @param reconciliation The reconciliation
 * @param vertx The vertx instance.
 * @param logContext A string used for context in logging.
 * @param logState The state we are waiting for use in log messages
 * @param pollIntervalMs The poll interval in milliseconds.
 * @param timeoutMs The timeout, in milliseconds.
 * @param completed Determines when the wait is complete by returning true.
 * @param failOnError Determine whether a given error thrown by {@code completed},
 *                    should result in the immediate completion of the returned Future.
 * @return A future that completes when the given {@code completed} indicates readiness.
